Tektronix Inc. adds full electrical verification and conformance test support for JEDEC DDR4, DDR3L and LPDDR3 memory standards to its oscilloscopes.

As JEDEC standards become faster and use less power, it is becoming harder to debug and validate devices. Faster read/write access and lower operating voltages of the new standards require improved signal fidelity from test fixtures. DDR4 introduces more complex tests such as variable VRef, Eye Masks and Jitter.

With the only oscilloscope-based JEDEC conformance solution in the industry that supports all variants of DDR, Tektronix speeds up engineering PHY verification of JEDEC standards testing.

The support for the next generation memory standards is integrated in the company's DDRA analysis software and is available for MSO/DPO/DSA70000, DPO7000 and MSO/DPO5000 Series oscilloscopes. Automating test setup and execution, DDRA eases design conformance with memory standards because if a memory system fails a conformance tests, designers can switch to debug mode and use tools like the Visual Trigger capability on Tektronix oscilloscopes to isolate events of interest for deeper root-cause analysis with the DPOJET Jitter and Eye measurement toolkit.

Tektronix also offers new interposers (DIMM, PoP and embedded) for DDR4 and LPDDR3. The controlled impedance and trace length matching on these new interposers in combination with de-embedding filters for the oscilloscope ensure an accurate representation of the signal.

In addition to these important updates, Tektronix offers in-depth test support for memory including high channel count memory system validation with the TLA7000 Logic Analyser, along with capture of both logic and analogue signals with the MSO70000 Series. The Tektronix MSO70000, the industry's highest performing mixed signal oscilloscope, is ideal for integration of command-address bus logic capture on digital channels for precise read/write burst detection.

The new DDR4 and LPDD3 interposers and updated DDRA software will be available in Q1 13, with prices starting at Rs.3.13 lakh ($5,910). DDRA support for DDR4, DDR3L & LPDDR3 will be a free upgrade to existing users.
